WASHING, RINSING, AND MAGHINE.

Specification of Letters Patent.

Patented Aug. 5, 1919.

Application filed February 15, 1918. Serial No. 217,416.

To all whom it may concern:

Be it known that I, JOSEPH MARIE ETIENNE FRANO, engineer, of St.Vallier, Drome, France, a citizen of the French hep-ublic, have inventeda certain new and useful Improved Washing, Rinsin and Wringing Machine,of which the fol owing is a specification.

The object of this invention is to Unite in a single device apparatusfor performing the three operations of washing, rinsing and wringingarticles of clothing.

In the annexed drawings Figure l is a Vertical section of the operativepart of the improieqd machine in position for washing an r1 ing,

Fig. 2 is a similar section in the position of wringing,

Fig. 3 is a cross-section on line 33 of The machine comprises a hollowcylinder 0; constructed of wood or of non-oxidizable metal provided withtwo hollow trunnions b b turning in bearings 0 c on on a suitable frame.The one trunnion 12 carries a pinion d to be driven by a chain or wormby means of a hand crank or motor so as to rotate the cylinder on itsaxis.

In the cylinder a is a plunger 5 movable along the whole length of thecylinder. A screw shaft f engaged in the trunnion b which is screwthreaded for the purpose, effects the translatory movement of theplunger 6, the said shaft being rotatable by means of a handle arrangedon its squared end 9.

The screw shaft f is hollow and has adjacent its piston openings itthrough which the water or washing solution conveyed throu h the shaftis introduced into the cylin er.

The second trunnion b is also hollow and serves for the outlet of theliquid, it is provided with a perforated plate 6 preventing the passinout of the linen or other articles. A remova le lug b closes the passagein the trunnion during the washing operation.

The linen or other articles of clothin are introduced into the machinethroug an opening closed by a door 7'.

The washin and rinsing is effected by rotating the cy inder. Ribs k arearranged along the walls of the cylinder and stir the linen and cause itto roll on itself effecting complete and uniform penetration by theliquid employed and causing thorough washing or rinsing as the cylinderrevolves.

For wringin the cylinder is maintained stationary but t e piston e ispushed inward by means of the screw shaft f so as to expel the Waterthrough the trunnion 12 What I claim as my invention and desire tosecure by Letters Patent of the United States is A combined washing,rinsing and wringing machine comprising in combination a rotaryimperforate cylinder having hollow trunnions, one of which is internallyscrewthreaded, bearings for said trunnions, a hollow screw shafttraversing said screw threaded trunnion, an imperforate piston carriedby said screw shaft movable lon tudinally in said cylinder and means orrotating said cylinder.

In witness whereof I have signed this specification in the presence oftwo witnesses.
